Qısa məlumat

TlInSe2 crystals were grown by Bridgman method. The thermal conductivity coe±cient was studied in the temperature range of 80–600K, along and perpendicular to the parallelepiped sample layers. The corresponding parameters of the TlInSe2 crystal were calculated based on the performed experiments. The results of the performed analysis have shown that the theoretical calculations and experimental results are of the same order, while the obtained and calculated values differ from each other by a factor of two. The temperature dependence of the thermal conductivity coe±cient of TlIn1-xDyxSe2 solid solutions is also studied. Moreover, effect of the gamma irradiation on the temperature dependence of the thermal conductivity of the TlInSe2 crystals were studied.
